The SNAP-AILC input module works with 2 mV/V and 3 mV/V load cells as a load cell front end. Using a separate 24 VDC power source (purchased separately), the module provides isolated 10 VDC bridge excitation for up to four 350 ohm or 415 ohm load cells.

An LED on the module’s top indicates that 24 VDC are present at the top connector and that excitation is being provided to the load cell.

Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley RSLogix PLC system, such as ControlLogix, MicroLogix, or CompactLogix.

NOTE: In addtion to SNAP PAC brains and R-series controllers, this module also works with the following legacy brains, if they have firmware version R6.1c or newer: SNAP-B3000-ENET, SNAP-ENET-S64, SNAP-UP1-ADS, and SNAP-UP1-M64.

Also see the SNAP-AILC-2, which works with 3 mV/V and 4 mV/V load cells.

The SNAP-AILC and SNAP-AILC-2 load cell input modules each provide one channel of transformer and optically isolated analog-to-digital conversion for load cell inputs. These modules also provide isolated 10 VDC bridge excitation for up to four 350 ohm load cells.
